My invention relates to containers such as bottles and the like, and particularly to containers designed for holding pharmaceutical or chemical preparations in'liquid form.

It is well known that in pouring a liquid from the neck when the bottle is tilted back to its vertical position, and, since the drop hangs from s the' outer edge of the neck, when the bottle is m righted the drop usually runs down the outside of the bottle. Furthermore; when the bottle /is placed upright, the liquid remaining on the edge of the neck usually spreads over the top of the neck of the bottle, forming a film of liquid thereis extremely objectionable when the liquid is of a corrosive or sticky nature or'tends to harden or deposit crystals on standing. Such bottles are dangerousto handle it the liquid is corrosive 2 and present an extremely unsightly. appearance when streaked with colored or sticky liquid. When caps are applied to receptacles of this type thefllm of liquid on the top of the neck tends to corrode or rust the cap and threads, contarninating the liquid and rendering it extremely diillcult'to remove the cap-after the bottle has stood for some time.

30 subject to this objection, and for this reason "paint cans are not ordinarily provided with vide considerable advantages over closure of other types for use on containers having liquids therein which tend to evaporate.

Attempts have been made to overcome the disadvantages inherent in bottles formed with rounded upper edges at the top of the neck by forming an outwardly turned tapering 111; which 40 is considered to reduce the amount of liquid adhering to the edge of the bottle. However, even with such construction the outlet opening in'the neck of the bottleis circular so that the liquid in g over the edge of the neck flows over a 4g relatively large portion of the circumference thereof, wetting the same and causing the liquid to flow laterally over the top of the neck when the of-the cap is not materially reduced.

vide containers with internally threaded necks the container-being closed by an externally a bottle a drop of the liquid always adheres to 15 on. This characteristic of bottles or containers Containers for'paint, varnish, lacquers and soforth, which tend to harden on drying, are also threaded necks, although threaded closures probottle is rlghted so that'corrosion and sticking it is common practice to proiormed with an externally located pouring spout,

ever, this construction is not adapted for use on bottles or glassware wherein the pouring spout is liable to be injured during shipment or handling of the bottle.

In accordance with my invention, the'foregoing objections and difficulties presented by the .use of bottles and containers of the prior art are overcome and a container provided which is formed with an externally threaded neck adapted I to receive and engage an internally threaded cap formed with complementary threads, the neck being provided with a pouring spout designed to be covered by'the closure member and formed to confine the liquid being discharged from the container to a limited area of the neck of the container. The provision of a pouring spout serves to prevent the flow of liquid down the outside of the bottle or laterally about the top of the neck when the bottle is rlghted.

In the present invention the container is provided with a threaded neck having a pouring spout formed thereon. However, in the present instance the neck is threaded substantially to the top thereoffand the pouring spout may be located in whole, or in part, within the threaded portion of the neck.

One of the objects of my invention is to prevent the flow of liquid down the exterior of the neck or laterally over the top of the neck of a container.

Another object of my invention is to prevent the corrosion and sticking of threaded caps to the necks of containers.

A further object is to provide a container having an externally threaded neck formed with a pouring spout thereon. U

Another object is toprovide a container having a pouring spout adapted to be covered by the closure for the receptacle.

"Afurther object of my invention. is to provide a bottle adapted to contain pharmaceutical or chemical preparations in liquid form which is free from the difllculties and disadvantagesinherent in bottles formed with circular outlet .openings.

Another object of a container having a neck threaded substantially to the top thereof and havingw, pouring spout formedin the neck. i

i'hese and other objects and features of myinvention will appear from the following description of preferred forms thereof, in which Flg. 1 is a plan view of a preferred structure as applied to a bottle; I v

Fig. 2 is a vertical sectional view of a bottle my invention is to provide embodying my invention.

with a cap thereon taken Fig. 1.

Fig. 3 is a perspective of a bottle having the neck thereof formed as shown in Figs. 1 and 2,

g with the cap removed.

Figs. 4 and 5 respectively, show a side and a of structure perspective of an alternative form The thread 6 at the point I 0 is interrupted for a sufficient distance to permit the formation of a pouring spout ii. The pouring spout is formed by a contraction of the material from which the neck is formed at the points IE on either side of the spout l2 and within the space Ill in the interrupted portion of the thread 6. The interior of the neck of the container is substantially cylindrical throughout the portion l4, thereof and is formed with depressed portions It on either side of the pouring spout I 2. The pouring spout thus constitutes an angularly formed lateral projection on the neck of the container which serves to confine the liquid'as it is poured therefrom. I prefer to construct the pouring spout with inwardly and sloping lower sides so as to cause liquid to drain back into the bottle from the pouring spout when the bottle is rlghted after pouring liquid therefrom. a

The top of the neck of the container is preferably flat, so that the entire. top oi the neck lies within a single plane. The neck thus provides a flat surface against which a packing member may bear to seal the container against leakage during handling and shipping thereof.

A cap l8 formed with a continuous thread 20 is adapted to engage the thread 8 on the neck of the container. Packing member 22 is carried by the cap inthe top thereof so that upon screwing the cap down on to the neck of the container the packing member will engage the top of the neck to seal the container against leakage.

By this arrangement, the container is formed with a pouring spout within the threaded portion of the neck thereof and at. the same time the usual threaded cap employed for closing such containers may be used. The outer extremity of the pouring spout I2 is locatedin alignment with, or within the inner diameter of the thread 6, as determined by the vertical portion of the neck of the bottle. For this reason the pouring spout does not interfere in am way with the application or, the removal of the cap from the container. When the cap is applied the. pouring spoutis wholly covered by the cap so that injury thereto in handling the container is avoided.

In the alternative form of the invention. illustrated in Figs. 4 and 5, the thread I is formed so that it begins at one side of the'pouring side I! and terminates at the opposite side thereof. The pouring spout is thuslocated between the ends of the thread and does not interfere in any way with-the application of a cap thereto. In

this form of the invention the outer extremity of the pouring spout I! may be positioned so that it extends into the thread on the cap forming in effect a portion of the thread i. This construction .has the added advantage that the pouring spout I! may extend beyond the vertical portion of the neck 4 and into alignment with the outer diameter of the thread i. For this reason the on the line .2-2 of pouring spout I2 may be formed somewhat larger than in the construction illustrated in Figs. 1, 2i, and 3, without interfering with the application of the cap to the neck of the bottle.

In the drawing I have illustrated bottles in which the edge of the top of the neck is flat. However, the edge may of course be rounded .or bevelled if desired, but in any case I prefer that the top of the neck should be entirely in a single plane so as to provide a suitable surface against which the packing member may engage to seal the container against leakage.

While I have illustrated and described two alternative forms .of my invention, it will be ap- Parent that the invention is not limited to these particular structures or to the use thereof on bottles or glass receptacles, but may be applied to other containers whether formed of metal, resinous compositions or other material. It should therefore be understood that I do not wish to confine my invention to the preferred forms thereof herein illustrated and described except as defined by the claims.
